Definitions
- the invention relates to a bypass-switchable hydraulic bearing, in particular for use as an engine mount in a motor vehicle, - according to the preamble of the main claim.
- Another option utilizes a precision manufactured rotary valve which is pneumatically actuated by a sealed shaft from outside the bearing. Disadvantages: operation by vacuum; not streamlined; Switching noises. For vacuum actuation, at least one solenoid valve is required, which causes costs and must be accommodated in the package of the vehicle. This type engine mounts is quite expensive, since small tolerances must be maintained. The passage of the shaft to the outside can cause sealing problems. By sealing the rotating shaft quite high operating moments are required. In addition, it is generally regarded as disadvantageous that vacuum is required in the known method. Laying vacuum lines is expensive. If the engine mount or the lines are damaged, the pneumatically operated brake booster should also be affected. If in the future electrically operated brakes ("brake by wire”) prevail, then diesel vehicles no longer have a vacuum pump that could serve to control pneumatically actuated engine mounts.
- the object of the present invention is the description of a Electromagnetically switchable hydraulic bearing, which is inexpensive to produce and the can be actuated streamlined.
- the invention relates to a throttle unit in a partition plate of a hydraulic muted camp.
- Partition plates usually have a damping channel and a Decoupling unit.
- a bypass switchable bearing includes a switchable one Bypass channel, which is opened in idle mode of the vehicle and a direct Connection between working chamber and compensation chamber produces. This results a reduction of the dynamic bearing stiffness and thus an improvement of the Vibration behavior of the vehicle.
- the bypass by means of a thin slide to open and close.
- This slider is operated by a coil-equipped magnetic circuit. Electrotechnically, it is a linear drive, in which the force is applied to a current-carrying conductor in the magnetic field (Lorentz force).
- the drive type "linear motor” according to the invention is not limited to a translatory slide but can be transferred to a rotatably mounted disc, wherein in one position by two aligned holes a bypass is opened.
- the coil is preferably located on a turntable and makes a movement about a bearing fulcrum.
- the return of the electric current can be used to generate power, if this is also in a magnetic field, however, the opposite polarity reversed have to be.
- the disadvantage is the larger space requirement.
- a permanent magnet can also be a coil, which wound around the iron circle is to generate the magnetic field.
- z. B an oval bypass geometry can be selected.
- a streamlined and in the dimension very variable bypass geometry can be realized.
- the magnetic drive is installed inside the bearing.
- the slider may be thinner than in the rear, which is the coil receives. This allows very short bypass channels and reduces the Flow resistance of the slider.
- the bypass can be made very large, since the drive (for example, in contrast to Solenoids) operates over the entire stroke with the constantly large force. It is therefore also conceivable an application in which a large bypass higher frequency (> 100 Hz) is tuned (fighting booming when driving at certain speeds).
- a decoupling membrane reduces the effect desired by opening the bypass (stiffness reduction).
- the clamping is done by an oblique nose, z. B. side of the slider.
- the kinematic reversal of the electromagnetic slide drive is of the Invention comprises. Thereafter, a coil is fixedly arranged on the partition plate, while a coil driven by the permanent magnet to the magnet coupled slider moved. Since in this case the coil is arranged stationary, can also the power supply are fixed.
- FIG. 1 embodiment of an inventive switchable Hydraulic bearing 2 has a rubber-elastic, rotationally symmetrical spring element 4.
- This spring element 4 is on the one hand axially with a first connection part 6a and on the other hand connected to the cylindrical wall 8a of a cup-shaped housing 8.
- a second connection part 6b is mounted.
- Spring element 4 and cup-shaped housing 8 enclose a hydraulic volume 10.
- Das Hydraulic volume 10 is by means of a partition plate (partition wall, nozzle plate) 12 in one Working chamber 10a and a compensation chamber 10b divided.
- the partition plate 12 on a throttle channel 14 which the Connect working chamber 10a with the compensation chamber 10b.
- the compensation chamber 10b is by means of a membrane 16 against the atmospheric pressure Surroundings demarcated.
- the bearing stiffness of an elastically supported Reduce the motor by opening a bypass 18 located in the partition plate 12 the bypass opening 18 is associated with a transverse bore 20 provided slide 22 (Details: see Fig. 2 to Fig. 8), wherein the transverse bore 20 in the manner with in the partition 12 located bypass opening 18 is aligned, that depending on the position of the Slider 22 located transverse bore 20 located in the partition wall 12 bypass opening 18 is closed or open. That is, the switchability of the bypass 18 becomes realized by the transverse bore 20 provided with slide 22.
- the partition plate 12 shown in section in Fig. 2 consists of a top 12a and a Lower half 12b. In between are the slide 22, which move in a guide can, and a magnetic circuit 24.
- the transverse bore 20 of the slider 22 is opposite to Bypass hole 18 moved so that the bypass is closed here in total.
- the drive of the slider 22 is carried out electro-magnetically by means of the so-called Lorentz force.
- that of the transverse bore 20 opposite end of the Slider 22 a magnetic circuit 24 (magnetic flux ⁇ , 26) on.
- the magnetic circuit 24 (permanent magnet system) - left in Fig. 2 - consists of a Permanent magnet 28 and an iron circle 30 which forms the pole pieces and a Magnetic field (magnetic flux ⁇ , 26) generated in the area in which the rear, with a coil 32 provided part of the slider 22 is immersed with the coil (coil pocket 34, Fig. 3 and Fig. 8).
- the slider 22 is made of non-magnetic material (A1 or Plastic) and contains a coil 32 located in the coil pocket 34 of the slider 22, which is perpendicular to the part within the magnetic field 26. The return of the coil 32 must be outside the magnetic field 26 in this embodiment.
- When energizing the coil 32 acts a force in the longitudinal direction of the slider 22 perpendicular to Magnetic field 26 and perpendicular to the electric current I, 36 (right-hand rule). Becomes reversed, so sets an opposite direction of movement.
- the circular part of the partition plate halves 12a, 12b is below the GummitragMechs (rubber part, 4) attached, the angular part with the magnetic circuit 24th outside the camp 2.
- the magnetic field 26 does not have to be particularly homogeneous. It is also conceivable to be aware designed inhomogeneity in the way that the fields for the position "bypass open” and “Bypass closed” are larger than in the middle range of the movement. That could be the power to overcome the slightly higher stiction can be increased.
- the current I, 36 can be reduced to only to hold the position of the slider 22.
- the bore 20 of the Slider 22 in alignment with the bore (bypass opening 18) of the surrounding Partition plate 12 (upper and lower part of the partition plate 12a, 12b, Fig. 2).
- This can be a very streamlined bypass geometry can be realized.
- the partition plate 12 contains nor the "normal" long damping channel 14 (Fig. 2, right) and a Decoupling membrane 38, which ensures that the damping only at larger Vibration amplitudes begins.
- the problem with bypass bearings 2 is that the Decoupling membrane 38 for the bypass operation is also active and the desired effect (Reduction of dynamic stiffness) is disturbed.

Abstract
Description
Die Lösung mit Bohrung und Pfropfen ist nicht optimal, da der Pfropfen eine strömungsgünstige Flüssigkeitsschwingung behindert. Diese ist aber notwendig, um im Motorlager eine gute Schwingungstilgung und somit eine niedrige dynamische Steifigkeit zu bekommen.
Nachteilig ist, dass die Strömungsführung nicht verlustarm realisiert ist. Nachteilig ist auch, dass die Betätigung in Richtung der schwingenden Flüssigkeitssäule wirkt. Im geschlossenen Zustand muss also eine relativ starke Feder den Stempel gegen die Bypassbohrung drücken. Dies hat zur Folge, dass zum Öffnen der Elektromagnet gegen diese relativ starke Feder arbeiten muss, also recht stark und somit groß und teuer ausgeführt sein muss. Auch im geöffneten Zustand fließt ein hoher Strom durch die Spule, wodurch sich das Lager stark erwärmt. Durch die Anordnung der Spule mit Anker baut das Lager recht hoch. Der Anker hat zwei Endanschläge. Beim Erreichen dieser Anschläge können Geräusche entstehen.
Nachteilig ist, dass bei diesen Lösungen Vakuum benötigt wird. Von den meisten Automobilherstellern werden elektrisch betätigbare Ventileinrichtungen bevorzugt.
Zur Vakuumbetätigung wird mindestens ein Magnetventil benötigt, das Kosten verursacht und im Package des Fahrzeugs untergebracht werden muss.
Diese Art Motorlager ist recht teuer, da geringe Toleranzen eingehalten werden müssen. Die Durchführung der Welle nach außen kann Dichtprobleme bereiten. Durch die Abdichtung der sich drehenden Welle werden recht hohe Betätigungsmomente nötig. Außerdem wird generell als nachteilig angesehen, dass bei dem bekannten Verfahren Vakuum benötigt wird. Die Verlegung von Vakuumleitungen ist teuer. Bei Beschädigung des Motorlagers bzw. der Leitungen ist eine Beeinträchtigung des ebenfalls pneumatisch betätigten Bremskraftverstärkers zu befürchten.
Wenn sich in Zukunft elektrisch betätigte Bremsen ("brake by wire") durchsetzen, dann haben Dieselfahrzeuge keine Vakuumpumpe mehr, die zur Ansteuerung pneumatisch betätigter Motorlager dienen könnte.
Der apparative Aufwand für die Schaltbarkeit des Lagers erscheint unverhältnismäßig hoch. Bei einem billig hergestellten Getriebemotor ist die Zuverlässigkeit nicht gewährleistet.
Die erfindungsgemäße Antriebsart "Linearmotor" ist nicht auf einen translatorischen Schieber beschränkt sondern kann auf eine drehbar gelagerte Scheibe übertragen werden, wobei in einer Position durch zwei fluchtende Bohrungen ein Bypass geöffnet wird. Dabei befindet sich die Spule vorzugsweise auf einer Drehscheibe und macht eine Bewegung um einen gelagerten Drehpunkt.
Vorteilhafterweise wird der Magnetantrieb innerhalb des Lagers installiert.
Mit Hilfe eines inhomogenen Magnetfeldes, das die Endpositionen der Spule stärker durchflutet, kann die Haftreibung des Schiebers besser überwunden werden.
